Towns DUMP BODY.

Application filed J'anuarylO, 1924; Serial No. 685,332.

Toall whom it may concern.

Be it known that we, JOHN C. GAY, l-tALr r E. SMrrH, and HARRY J. Quinn, citizens of the United States, residing at (iralion, in the county of Crawford and State of Ohio, have invented certain new and useful Im 'n'ovements in Power Dump Bodies, of whichthe following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to power operated dump bodies. v

It is the object of our invention to provide a dump body of simple and powerful construction which may be operated by hand power or other motive power with the least expenditure of energy for the control and actuation of the body and its load.

It is a further object of our invention to provide a body, 111 which the mechanism has a maximum leverage with a minimum height of the body from the ground and from the frame of the vehicle.

It is a further object of our invention to provide self-adjusting mechanism which will accommodateitself to varying positions of the body.

It is anadditional object of our invention to provide a body which is so braced that it will not warp out of position and so arranged that if any warping does occur, it may be eliminated by the adjusting means provided.

It is a further object to provide the pivotal point of support as low as possible to assist in lowering the center of gravity and to maintain the equilibrium of the body.

Referring to the drawings:

Figure 1 is a side elevation of the com plete body and its actuating mechanisn'i mounted on a chassis frame.

Figure 2 is a section on the line 2-2 of F igure 3, showing the driving worm and gear.

Figure 3 is a plan view of the same mechanism with thecover removed from the casing.

Figure leis a top plan view with the bottom broken away from the body and with some of the braces broken away and supplementary frame members to show the arrangement of the tie rods and the body upon the frame.

Figure 5 is a section through the protecting casing and nut mounted on the actuatnected to the main frame by the U-bolts 3.

Pivoted upon the supplen'ientary frame 2 on across shaft f'held in position laterally by the pins 5 are the upwardly extending brackets 6, which have broad upper ends for the distribution of the load upon them. These brackets the bolts 7. 1

Intermediate the frames 2, mounted on the shaft 1:, are the upwardly projecting arms 8. These arms 8 have mounted in their upper ends thetrunnions 9 of a screw block 10, in which works the screwll of the operatin shaft 12. This block carries on its trunnions freely pivoted thereon the metal housing 13, which prevents dirt and grit from injuring the screw 11.

The other or forward end of the shaft12 is provided with a worm wheel 14 keyed thereto and with the bearings 15 and 16. The end of the shaft passes through the housing 17 and through the channel iron 18, which forms the forward abutment for the thrust of the shaft and for carrying the easing 17.

Meshing with the worm wheel 14: is the screw 19 mounted on the actuating shaft 20 which may be actuated by a hand wheel 21 or any other suitable source of power.

It will be notedthat the channel member 18 is pivotally mounted as at 22 in the sup plementary frame members 2, so that as the shaft changes its position in actuating the body it will rock with the shaft.

The body 23 is provided with the following means for aligning it and preventing it from warping. attached as at 25 to the frame of the body, the frame being designated 26 at a point just forward of the pivotal support of the body on the supplementary frame. The

forward end of the tie rodis located diagonally at the forward corner of the body, where it projects through an angle iron secured to said body, as at 27. The end of the rod is threaded and carries a nut 28 for adjusting the tension. This tie rod passes are attached to the body by Reach rods 2% have one end beneath the frame members 29 and 30 and the rods themselves cross over each other at a point between these two frame members.

We desire to comprehend within our invention such modifications as may be necessary to adapt it to varying conditions.

Having thus fully described our invention, what we claim as new and desire to secure by Letters: Patent, is?

1. In a ,dump body construction, a body, means to pivot-ally support said body on a frame, a frame and a lever extending upwardly from said pivotal support and connected thereto, actuating means extending from said lever to a remote point, and means for controlling said actuating means.

2. In a dump body construction, a frame, means on said frame for pivotally supporting the body, downward extending brackets extended from said body mounted on said pivotal means, an upward extending lever from said pivotal means, a nut carried by said lever, a worm shaft adapted to actuate said nut and means for actuating said worm shaft.

3. In a dump body construction, a frame, means on said frame for pivotally supporting the body, downward extending brackets extended from said body mounted on said pivotal means, an upward extending lever from said pivotal means, a nut carried by said lever, a worm shaft adapted to actuate said nut, means for actuating said worm shaft, and means to rotatably support the other end of the worm shaft to adjust its position as the worm moves relative to the nut.

a. In combination, a frame, upwardly extending brackets pivotally mounted on said frame, a dump body mounted on said brackets, upwardly extending arms mounted on said pivotal supporting means, a nut journaled between said arms, a worm on a worm shaft, travelling in said nut for actuating the arms and tilting the body, a worm shaft, means for pivotally supporting the free end of said worm shaft, a transverse shaft extending to one side of the frame, and means connecting said transverse shaft and worm shaft, whereby the actuation of the transverse shaft will actuate the worm shaft.

5. In combination, a. frame, a transverse shaft journaled therein, brackets mounted on said shaft extending upwardly, a body mounted on said brackets, arms extending upwardly from said shaft connected thereto, a nut rotatably mounted on said arms, a diagonally disposed worm shaft mounted in said nut, the nut being located in the upper end of the arms, a. transverse thrust member pivotally supported between the frame members and carrying one end of the shaft, a transversely located actuating shaft geared to the worm shaft, gearing connecting said shaft, and a hand wheel for actuating said transverse shaft.

6. In OOHlblIlillllOD, a frame, a transverse shaft journaled therein, brackets mounted on said shaft extending upwardly, a body mounted on said brackets, arms extending upwardly from said shaft connected thereto, a nut rotatably mounted on said arms, a diagonally disposed worm shaft mounted in said nut, the nut being located in the upper end of the arms, a transverse thrust member pivotally supported between the frame members and carrying one end of the shaft, a transversely located actuating shaft geared to the worm shaft, gearing connecting said shaft, a hand wheel. for actuating said transverse shaft, and a gear box casing mounted upon the thrust member.

7. In combination, in a dump body construction, a frame, a pivotal support for a dump body on the frame, a. pivotal support for an actuating shaft mounted on said frame, an actuating shaft extended to a point above the first i'nentioned pivotal support, and an arm extending from said piv otal support to said shaft to be actuated thereby, and means for actuating said actuating shaft.

In testimony whereof, we allix our signatures.
